    "answer": "WCS1 and WCS2 support a 40-unit wet external-output subtotal, 30 from A counted once plus ten from C. B's 20 dry-solids units cannot be added to wet mass without its missing conversion. WCS3's internal return does not add external flow, and the remaining balance evidence is incomplete. Preserve the common run lineage but leave closure unresolved rather than force a neat total by duplicating a meter export or mixing bases.",
